' 1n ent of the strikerstoward or away from each other; also, anindependen't connection between the actuating mechanism of the bell and the push-button or its which it is sounded.

Figure 1 is a plan view of a bell embodying my invention with the gong removed and' parts broken away to show the construction;

Fig. 2 is a sectional view through the center of Fig. 1. Fig. 3 is a detailed View of the connecting-piece.

Referring'to the drawings, A denotes the base of. a bell. B is an arm carried thereby and supporting at its free end the" gong O.

D D are plates forming a suitable support for the mechanism by which the striker-bar is operated. I v

The actuating mechanism consists of the spiral E, having at one end a fiat portion e, which fits a slot a in the stationary plate b and is capable of lengthwise movement therein. The connecting means between the spiral and the striker-bar may be of any well-known type; but, as shown in the drawings, it is a train of gears, counterbored at m and having a slot n in it through which the spiral passes. The object in counterboring the hub is to allow of the use of a spring d of suflicient length to return the parts to their normal position and still retain the compact form of the bell." It is evident that as the flat portion e of the spiral passes lengthwise through the slot a it is prevented from rotating and that the gear or its equivalent, through which the spiral itself passes, is rotated and inturn transfers its r0- tary motion through the train of gearing to the striker-bar.

G is a loose connecting-piece between the push-button g and the spiral E, having at one equivalent by one of which, a, has a hub Z,

house's, &c., and the thickness of the casings 6o or the doors'to which they may be attached is variable. In putting up bells for the market the connecting piece G is made long enough to meet all requirements and may be readily cut to any length desired. The object in doing this is to allow of all the spirals being made exactly alike and no longer than necessary to operate the strikers and alsg to permit adjustment of the "connecting-piece between the actuatingmechanism and the push-button. Another. ad vantageigained by the use of this construction is a greater simplicity in fastening the bell to a door or casing.- AtH is shown my improved form of strikerbar, which allows of the adjustment of the strikers toward or away from each other. This is accomplished by bending the strikerbar up, as at h h, and outwardly, as at i 'i, the ends 2' 2" being slotted to support the strikers k 70. It often happens in assembling bells that the strikers are too near or too faraway from the gong to sound it properly and with the best results, and there has as yet been no way devised by which this trouble can be readily overcome. the upturned portions h hi can be easily bent toward or away from each other and the strikers so adjusted that they operate with'the best results. This is an important improve- In my improved striker ment, which will be readily recognized as such by manufacturers.

' It is not important to the proper working of my invention that a spiral be used, as any equivalent construction will operate with as satisfactory results. 1

- I claim as my invention- '1. In a bell, a base, a stationary plate pro= jecting above the surface of the base, fastened thereto, and slotted to receive the flattened end of a spiral, a striking mechanism roo actuated by a spiral, said spiral having one end flattened to fit the slot in the stationary turn the parts to their normal position, one

' gear and the strikers, and means for impartthe strikers,

the parts to their normal plate gear, and means located gear for returning position.

6. In a bell, a base having lugs diametrically opposite each other, plates extending between these lugs and attached to the bottom plate and capable of lengthwise movement therethrough, and means of imparting a lengthwise movement to the spiral.

2. In a hell, a base, a slotted stationary plate projecting above the surface of the base, the strikers, a gear held against lengthwise movement and slotted at its center, a spiral passing through the slot in the gear and havand top thereof; the operating mechanism for ing its flattened end pass through the slot in the strikers supported between said plates, a

the stationary plate, saidspiral being capable of a limited lengthwise movement, a c'onplate attached to the upper side of the lugs nection-between the strikers and the gear and having a slot through it, a spiral having mounted on the spiral, and means for iinparta fiat portion which passes through the slot ing motion to the spiral. in the said plate, a gear having a slot through 3. In a bell, the combination with the base which the spiral passes, and means for im- A, the gong C, the strikers H, the spiral E parting to the spiral a lengthwise motion.

7. In an operating mechanism for bells, the

and the slotted plate b, of a gear havinga recessed hub slotted to receive the spiral, constrikers, a spiral capable of lengthwise movement having a flattened portion at one on nections between said gear and the strikers, a shoulder on the spiral, means forimparting passing through a slot in a stationary plate, a connection between the strikers and the lengthwise movement to the spiral, an a spring arranged around the spiral between spiral, one part of which is mounted on a recessed hub having a slot through which the the shoulder and the "stationary plate b to respiral passes, a spring located in said recessed hub to return the parts to their normal position, and means for imparting lengthwise movement to the spiral to operate the parts as and for the purposes specified.

8. A rotary striker-bar for bells having a central portion, arms bent at an angle thereto and strikers attached to said arms, whereby 'said strikers may be adjusted toward or away from the gong.

9. A rotary striker-arm for bells having offset portions at each end joined to the central end of said spring being located in the recessed hub of the gear.

4. A mechanism for operating the strikers of a bell, oomprisinga slottedstationary plate, a gear slotted at its center, a spiral having a stop and a flattened portion beyond said stop, said fiat portion passing through the slot of the stationary plate and the spiral through the slot in the gear, connections between the ing motion to the spiral.

5. A mechanism for operating the strikers portion by substantially right-angle bends, ofabell comprising a slotted stationary plate, whereby the strikers may be adjusted toward or away from each other.
